Denny Krahe is a Running coach & the host of Diz Runs Radio. Today, we dive into HR and effort-based training. I and the podcast patrons ask the following questions: What are heart rate and effort-based training? And what are the benefits/limitations? How do you see runners misusing this form of training and what are some common misconceptions? Should HR zones change over time as you improve? Is low HR training beneficial for new, unfit runners or runners with higher than average heart rates?  Does an elevated heart rate or HRV indicate a lack of recovery?
